Abstract

Service-oriented architecture facilitates rapid development and management of large-scale distributed service-based systems (SBS), where new workflows are composed of available services. Besides services' capabilities, the qualities of services (QoS) also need to be considered in service composition in order to have high-quality workflows. The QoS profiles of services provided by their service providers may be inaccurate. In this paper, an approach is presented to improving the trustworthiness of the QoS information of services to facilitate the development of high-quality workflows in SBS. Our approach is based on identifying the deviation between the QoS profiles of the services claimed by their service providers and the QoS profiles determined by monitors and service user feedbacks. An example is given to illustrate the approach.
